Inhibitors of farnesyl-protein transferase

The present invention comprises analogs of the CAAX motif of the protein Ras that is modified by farnesylation in vivo. These CAAX analogs inhibit farnesyl-protein transferase. Furthermore, these CAAX analogues differ from those previously described as inhibitors of farnesyl-protein transferase in that they do not have a thiol moiety. The lack of the thiol offers unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol-dependent chemical reactions, such as rapid autoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. Further contained in this invention are chemotherapeutic compositions containing these farnesyl transferase inhibitors and methods for their production.

The present invention comprises an analog of the CA1A2X motif of the protein Ras that is modified by farnesylation in vivo. This CA1A2X analog inhibits the farnesyl-protein transferase and the farnesylation of certain proteins. Furthermore, this CA1A2X analog differs from most compounds previously described as inhibitors of farnesyl-protein transferase in that it does not have a thiol moiety. The lack of the thiol offers unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol-dependent chemical reactions, such as rapid autoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. The compound of the instant invention also incorporates a cyclic amine moiety in the A1 position of the motif. Further contained in this invention are chemotherapeutic compositions containing this farnesyl transferase inhibitor and methods for its production.

The lack of the thiol offers unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol-dependent chemical reactions, such as rapid antoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. Further contained in this invention are chemotherapeutic compositions containing these farnesyl transferase inhibitors and methods for their production.
